  • Patent number: 6188495
    Abstract: A transmission optical signal emitted from a laser diode is introduced in an S-polarized state to a polarization-reflection film formed on an inclined surface of a prism. This transmission optical signal is in a light quantity that is reflected by the polarization-reflection film to enter an optical fiber. With this configuration, an optical transmission-reception apparatus for a single-core bi-directional optical communication circuit enables an enhancement of the efficiency of introduction of the transmission optical signal into the optical fiber constituting the optical communication circuit so that a sufficient performance and reliability of the optical communication circuit is realized without increasing the light quantity emitted from the laser diode which outputs the transmission optical signal.

  • Patent number: 6185172
    Abstract: A rotation control apparatus which does not rely upon a drop of a signal is provided. A lower limit frequency and an upper limit frequency calculated based on generation patterns of run length limited codes which may possibly be generated stochastically are set as a frequency variation range. When rotation control is performed based on an error between a frequency of run length limited codes reproduced from a disk and a reference frequency while a PLL circuit is not in a locked condition, the reference frequency is varied between the upper limit frequency and the lower limit frequency. Then, the reference frequency which is currently used for comparison when the PLL circuit is put into a locked condition is stored as a fixed value and used as the reference frequency for later rotation control.

  • Patent number: 6184454
    Abstract: In a tone color map generating section, a tone color parameter and the effective time for making the tone color map effective are extracted from an SMF stored in a MIDI file database, and the tone color parameter is stored in a tone color map database. When a demand processing section receives a playback start position for starting the playback of the SMF, a read processing section reads the tone color parameter stored in the tone color map database in accordance with the playback start position, and generates time information indicating time to set the tone color parameter in a MIDI device. A sending circuit sends the tone color parameter together with the corresponding time information, and then sends a MIDI signal from the playback start position thereafter, stored in the MIDI file database.

  • Patent number: 6182240
    Abstract: A reproduction system includes a host apparatus and a reproduction apparatus for executing a reproduction operation with respect to a predetermined recording medium, both connected so as to mutually communicate. Defect management information is read from the recording medium for necessary address transformation so that the host apparatus can perform the defect management of the recording medium. When requesting the reproduction apparatus to reproduce data, the host apparatus transmits to the reproduction apparatus, physically-reading position information formed by performing address transformation in accordance with the defect management condition. The reproduction apparatus does not need to perform defect management when reproducing data from a read only medium but also a random access medium. This enables provision of a reproduction apparatus capable of using the random access memory medium, with the similar circuit size and cost of a reproduction apparatus adapted for only the read only medium.

The product includes material having a surface having many recesses, each having an opening of size d, where d is in the range 5-100 microns, a depth in the range from 0.2 d to d, or many grooves. In preferred embodiments, each groove or recess has an anchor portion. In some embodiments, each groove has a ridge portion at each of both edges of its opening. The angle of each groove to the surface of the material and each groove's depth and opening width are preferably in specified ranges. When the material is plated, part of the thin metal film enters the anchor portions of its grooves or recesses, so that the plated metal has superior capacity to resist peeling off of the plated metal.
